IMPROVEMENT- IN MALT-KlLNS.

The Schedule referred toiu these Letters Patent iand making part of thesame.

I, CIL-mons Puttane BnneKHmrnn, of Cincinnati, in the county ofl'iamilton .and State of Ohio, have invented certain Improvements inMalt-Kilns, of which the following is a specification,

Nature and Obcjcts ofthe Inrcniiont f vated some distance above theground, thereby insuringa supply of pure and dryair to the interiorofthe apparatus, by which means its cliicicncy is increased vand thelabor of attending'it.diminished.

The second part of my invention relates to that vpart of the kiln termedthe hopper, which, surrounding the cupola, extends up to the perforatedfloor, and which serves to conduct the heated air to the grain that isto be dried; and y The improvement consists in constructing thispart ofthe apparatus of metallic sheets or plates, having nWarLlIy-prOjectingiianges for supporting a lining composed of cement, tire-clay, or someother suitable plastic material, which will prevent the radiatiml ofheat.

General Description with` Ltyi/reizco lo the Drawing/ Figure l is avertical section of a malt-kiln embodying my improvements, one of theregisters for regulating the supply of air heilig represented open andthe other-closed.

Figure 2 is a section through a portion of the kiln taken at the linea'.

Figure 3 is a perspective view of a part of the metal casing or shell ofthe hopper, with a portion of the cement lining removed therefrom.

A represents thel furnace or-cupola, having the eustomary ash-pit- B,lire-chamber G, land vertical tine l), up which the heat ascends fromthc tire in said chamber U.

The pit D and tire-chamber U are provided, respectively, with doors l: band co', for the purpose ot'rcgulating the supply of air to the furnace,and to allow the replenishing of the fuel in the same.

Located a suitable distance above the yupper end of ue D is thecustomary slab or lintel E, which compels thc heated air arising fromsaid Hue to discharge itself laterally int-o the kiln, and noiI to takea direct central passage through the same.

The sloping4 top o of this slab or plate causes the deflection offsprouts, which may fall through the perforated floor of thedrying-room, and prevents them dropping into the mouth ot the furnace.

The walls ofthe cupola, after being carried up a propel' height, arediminished in thickness, so as to form a ledge, l", which serves as afoundation for a heavy casting or bed-plate, f, that surrounds thecupola on all four sides.

Projecting outwardly from this bed-plate are arms, 1i, for the supportof a rim, I, having a shoulder, i, for a purpose which will presentlyappear. p

Between tho arms H are openings J, through which fresh air ilows to theinterior of the apparatus, and the supply is regulated by means ofregisters, K, which are hinged at tfto the rim I.

The opening or closing ofthe'sc registers is controlled by cords orchains L.

Resting upon the ledge i, and arranged so as to incline outwardly fromthe cupola, is a number of metallicplates, M, preferably of sheet-iron,whose lower` edges are bent so as to form inwardlyprojecting tianges,Ju, that serve to support a lining, N. This lining may be composed ofcement, tire-clay, plaster of Paris, or any other suitable refractorymaterial that is a non-cmuluctor of heat and that can be applicd'in aplastic condition. This v filling is cheap, readily applied, and is, inevery respect, superior to the. expensive and heavy brick-work liningwhich has heretofore been employed in this part of a malt-kiln.

lhe metallic jacket or shell M ofthe hopper, if preferred, maybestiffened by angle-iron ribs, O, tha-t can extend from the top of rim Ito thcpcrtin'ated ioor l of Jthe drying-room.

rlhe sheet-metal plates composing the shell, together with theirangle-iron ribs, are united by rivets T.

'lhe oorl extends completely across the mouth of the kiln and rest-supon beams lt.

Bins or other receptacles, S, may be placed at the sides of the furnacefor the purpose of rcccivingthe sprouts which may be deflected fromlintel E and fall through openings J, and suitable troughs may bearranged around the cupolaJ for conducting the sprouts into saidreceptacles.

In all kilns which have heretotore been built it has been customary tolocate the air-ducts in the walls of the cupola, thereby increasing thcdimensions and cost of the same, and at the same time causing the kilnto occupy a large amount of valuable space, besides which, the openingsthat admitted air to said ducts were always situated ucar the ground,where the air is more or less impure.

It will be secu that the arrangement of air-openings .T renders my kilnfree from all these defects.

Another serious objection to thc old-tiishioned-kiln consists in thearrangement of heavy beams, wooden sheathing, and interior brick-lining,for which I have substituted the angle-iron ribs O, sheet-metal case M,and plastic filling N, thereby diminishing the weight, reducing the dostof construction, :unl rendering the kiln perfect-l y fire-proof.,v

If desired, `doors can be meule in the plates m, so as to afford accessto the interior of the hopper for the purpose of inspecting and cleaningthe-seme.

Cla-ilus.

I claim aslnew and of my inventionl. A malt-kiln, having the externaland elevated air-inlets J, which :ire closztble by registers K, or theirequivalents, substantially as herein described.

2. The combination' of' the sheet-metal case M M and plastic filling N,for the object herein set forth.

In testimony of which invention I hereunto set my hand.
